This allows decentralised decision making for large grained resource allocation - for example should we build a factory for shoes, or for toothbrushes? - and is a good thing, as central planning has been demonstrated to not work if applied to the whole economy. (the converse, no central planning to any of the economy, has also been demonstrated to not work!)
However that accumulation can be (and nowadays usually is) orchestrated by a corporate entity, which in an ideal world would be almost entirely beneficially owned by retirees on an equitable basis.
What has gone wrong, is that the benefits of productivity enhancements (since 1970?) have flowed to capital more so than to workers - which not least prevents them from forming capital themselves (savings/pensions), hence rising wealth inequality.
